The severity of the symptoms, which may include muscle pains, vomiting and confusion, depends on the extent of muscle damage and whether kidney failure develops. The muscle damage may be caused by physical factors, medications, drug abuse, and infections.
Also known as a subconjunctival hemorrhage, a broken blood vessel on the front of the eye is typically a harmless condition (although see below) that clears up within one to three weeks. Subconjunctival is the term used to describe the space located just beneath the conjunctiva (the clear surface of your eye).
A subconjunctival hemorrhage often occurs without any obvious harm to your eye. Even a strong sneeze or cough can cause a blood vessel to break in the eye. You don't need to treat it. Your symptoms may worry you. But a subconjunctival hemorrhage is usually a harmless condition that disappears within two weeks or so.
